Tungsten Needle
Tungsten needle normally divided into pure tungsten needle, rare earth needle and doped tungsten needle.It is mainly used for the high intensity gas discharge electric arc tube. The surface can be supplied in a shiny or matte; dependent upon thickness and width parameters.
Tungsten needle is suitable for TIG welding and other electrode materials because of its characteristics。

About Tungsten Needle
Tungsten needle normally divided into pure tungsten needle, rare earth needle and doped tungsten needle.
It is mainly used for the high intensity gas discharge electric arc tube. The surface can be supplied in a shiny or matte; dependent upon thickness and width parameters.
Application
Tungsten needle is suitable for TIG welding and other electrode materials because of its characteristics
The addition of rare earth oxides to the metal tungsten to stimulate its electron work function, making the tungsten electrode welding performance can be improved: the arc of the arc better performance, better stability of the arc column, the electrode burn rate is smaller. Conventional rare earth additives are cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide and thorium oxide.
All of diameter above 1.0mm could be provided.
